Bluetooth Receiver, Bluetooth Aux Adapter Bluetooth Receiver for Home Stereo with Hands-Free Calling Wireless Music Adapter, 3.5mm Male/Female Output Stereo Jack for Headphones/Car/Speakers

Great product

This is by far the best Bluetooth car receiver I've used. Fast connection and no buzzing with my Pixel 3a. I normally keep the receiver plugged into USB for power, but I love having the battery available when I need to unplug it to charge another device. A great value.

REVIEW UPDATE on 2/23/2022: After having used this device for over a year, I am changing my rating from 5-Stars to 3.5 for the following reasons: 1. This device keeps connecting and disconnecting with my iPhone at random times, as I had mentioned near the end of my original review (see below). Even after upgrading my iPhone from an iPhone 7 to an iPhone 11, this same issue STILL exists, which is VERY ANNOYING!! 2. As other reviews have mentioned, there is a humming sound that comes and goes on a regular cycle (about every minute or so, I didn’t time it) when I have the volume turned up on my car stereo. When I unplug this device, the humming cycle goes away. If I keep the volume on my car’s stereo lower and maximize the output volume on my iPhone and Echo Dot, then this humming is less noticeable. Other than that, this device is still working, still looks nice, and I use it every time I drive my car. I use its Answer button more than I expected, more than the one on my "Tunai Button Media Remote Control" since it is easier to press one button with no other buttons around it than a button surrounded by 4 buttons. The Answer button especially comes in handy when you need to redial a number — just tap it twice. ORIGINAL REVIEW on 11/20/2020: I'm so glad I came across this device so that I could connect wirelessly my iPhone 7 to my vehicle that does not have a Bluetooth stereo, but does have a 3.5mm Aux Input jack. If this is all this device did, I'd be satisfied. But it does MORE, which exceeded my expectations. It has a microphone, so I don't have to use my phone's mic during calls. Furthermore, since this unit is SMALLER than I expected, I was able to place it in a good location high up on my dashboard so that it faces my mouth, allowing others to hear me easily. Since this unit is black, it blends in nicely with my dashboard and I was able to hold it securely in place with a thick black wire I had laying around that I inserted into a small opening on my dashboard. On top of all this, it has a front-facing button for answering phone calls or pausing music, which is a nice touch, and side buttons for changing the volume on my phone or skipping songs when held. I don't use these button much, though, since I also bought a "Tunai Button Media Remote Control" steering wheel Bluetooth remote (I also highly recommend this too) to control these same functions more easily, but nice that these buttons exist, though, just in case the battery in my Tunai steering wheel remote dies. I was able to easily plug this device into a USB port in my vehicle and run a 3.5mm audio cable to my car stereo's aux input jack, so there is nothing for me to maintain (just set & forget). Everything worked as I had hoped right away without any issues and my first week-long trip with this device worked flawlessly! Thank you for creating this! Later I decided to add an Amazon Echo Dot to my vehicle, I was able to connect it up to this device wirelessly too via Bluetooth, and it worked -- AMAZING! Now I have Alexa playing through my vehicle's stereo, which sounds wonderful! Since this device supports Dual Link Bluetooth Connectivity, which I wasn't expecting, my iPhone still works too at the same time, for the most part -- I do get a lot of Bluetooth connects and disconnects on my iPhone when my Echo Dot is playing music, which I am still trying to figure out. My device did NOT come with any instructions, though, but their support answered my question quickly, which was nice! (Would be good if this info was included in their product Description above too). Here are the important instructions to be aware of: POWER ON & PAIRING: Hold Answer Button for 3 sec (LED flashes Blue & Red) Voice Prompts: - Power On - Pairing - Connected (When pairing for the first time, pick "Ralyin R1" on other device that you are paring with, like your iPhone, in its Bluetooth setting) POWER OFF: Hold Answer Button for 3 sec Voice Prompt: - Power Off ANSWER or END CALL, PLAY or PAUSE MUSIC: Tap Answer Button Once REDAIL: Tap Answer Button Twice VOLUME UP: Tap + (Plus) Button VOLUME DOWN: Tap - (Minus) Button NEXT TRACK: Hold + (Plus) Button for 1 sec PREVIOUS TRACK: Hold - (Minus) Button for 1 sec CHARGING: Red LED is ON; Red LED is OFF when fully charged IMPROVEMENT SUGGESTIONS: - Consuder using USB-C instead of micro-USB - Create a separate USB-C device that has two USB-C ports for pass-through charging and one 3.5mm port to split out the audio instead of your proprietary charging cable - Include a Tunai-like steering wheel control unit that seamlessly integrates with this device - Fine tune Dual Link Connectivity so that my iPhone doesn't keep connecting and disconnecting to this device whenever my Echo Dot is playing music via Bluetooth to this device Thank you again for all of your hard work on this wonderful device! Another unexpected surprise were the clear voice feedback prompts.

We were ever able to get it effectively working. But we waited too long to get a refund.

Battery not so great!!! Needs. A better battery life

Very happy🙂🙂🙂 it conects fast.

The sound quality is mediocre and the volume level is embarrassing I have to turn my car stereo all the way up to remotely here it at all

My car is old and featureless so I needed something to play music from my phone with. This worked perfectly for me. I also like that it comes with so many ways to connect so I can easily use it for headphones instead or connect to nearly anything.

Tengo con él un par de días, llegó a tiempo y lo he ocupado un par de ocasiones, funciona realmente bien las pruebas de distancia y batería aún no las realizo. Actualizare mi comentario con las pruebas. Finalmente, el tamaño es muy discreto tanto que los cables conectores se ven grandes a su lado.

I use it to connect my phone to my motorcycle sound system. Works well and more convenient than an auxiliary cord. However, it is no as loud as the direct connection but works well.

Es fácil de usar y transportar, es pequeño y no estorba, se ve discreto, iguala la calidad de audio por cable 3.5mm que es lo que buscaba. Lo malo es que dura muy poco la bateria, seria bueno agregar otro puerto para mantenerlo conectado a corriente. Lo bajo del auto para cargarlo. Baja un poco el volúmen normal del estéreo.

Great sound quality. The latency between audio and video was awful but if you are using it for anything that doesn't require lips to match the sound (radio, music, etc) then this is great. The cables are designed with the consumer in mind. I really wanted to like it but it didn't work for my needs so it's going back. It is small enough for a child to swallow it so be careful!

Buen producto fácil de usar cada recarga al 100 me dura 9 horas, lo único malo es que diminuye un 20% el sonido de mi estereo
